TStaticVar names

Just curious whether TStaticVar's are supposed to have a name when created on Clientside because I can't get them to display.

PHP Code:


		
			
//#CLIENTSIDE
...
temp.variable = "Fish";
temp.testing= new TStaticVar("Name_"@variable);
testing.one= "things";
testing.two = "stuff";
player.chat = testing;
...

Will output nothing.

But serverside..

PHP Code:


		
			
...
temp.variable = "Fish";
temp.testing= new TStaticVar("Name_"@variable);
testing.one= "things";
testing.two = "stuff";
echo(testing);
...

Outputs Name_Fish

Try using the 'name' variable to get it.

Indeed.

echo(testing.name)

Ahhh yep that did it. Thank you.

So what is TStaticVar()'s parameter used for?

It makes it less than ideal to store objects in arrays as you can't use .index() and other built in functions (because an array of objects will all have the name ""). Would have to run through the array checking .name for each element.

The name.

PHP Code:


		
			
new TStaticVar("MyObject");

MyObject.variable = value;

Just make sure you keep a reference to the object somewhere or the garbage collector will eat it.

PHP Code:


		
			
echo(allplayers.index(findplayer("account")));

I've also done checks like..

PHP Code:


		
			
if (findplayer("account") in players) {

  // stuff

}



if (findweapon("-System") in player.weapons) {

  // stuff

}

Edit: Further testing..

PHP Code:


		
			
//#CLIENTSIDE

function onCreated() {

  temp.a = new TStaticVar();

  temp.a.val = 2;

  temp.b = new TStaticVar();

  temp.b.val = 1;

  temp.c = new TStaticVar();

  temp.c.val = 3;

  temp.objs.add(temp.a);

  temp.objs.add("LOL MESSING U UP"); // It doesn't :)

  temp.objs.add(temp.b);

  temp.objs.add(temp.c);

  echo(temp.objs.index(temp.b));

  if (temp.c in temp.objs) {

    echo("this also works..");

  }

}

Now we all benefit for not having to use loops to compare objects :)

Jerret is right. You can compare objects as objects, rather than comparing their names.

PHP Code:


		
			
temp.pl = findPlayer("cbk1994");
temp.pl2 = findPlayer("cbk1994");
temp.pl3 = findPlayer("Grey");

echo(pl == pl2); // 1
echo(pl == findPlayer("cbk1994")); // 1
echo(pl == pl3); // 0

hence why you can also use "in" and functions like "index", as fowlplay said.

For stuff like this..

PHP Code:


		
			
//#CLIENTSIDE



function onCreated() {

  // Object-based Design

  new TStaticVar("Tree") {

    this.a = 30;

    this.b = 30;

  };

  temp.a = new Tree();

  temp.a.a += 5;

  temp.b = new Tree();

  temp.b.b += 2;

  temp.c = new Tree();

  temp.c.a -= 2;

  temp.c.b -= 4;

  // Display Values

  echo(temp.a.a SPC temp.a.b);  // 35 30

  echo(temp.b.a SPC temp.b.b);  // 30 32

  echo(temp.c.a SPC temp.c.b);  // 28 26

}

Appreciated you can do that if you have access to a var referencing the obj but what I was trying to do something along the lines of:

PHP Code:


		
			
//#CLIENTSIDE
function addToList(account) {
  this.objs.add(new TStaticVar(@account));
} 

function checkList() {
  return (player.account in this.objs);
}

Which on the serverside would work. (If you changed checkList to be serverside friendly)

Was trying to see if I was doing it wrong somehow as if you output the array, rather than each of the objects having the name you'd assigned them, they all have blank names.

I'll just change the way its being handled but thanks guys

I'm pretty sure doing an equality check on objects implicitly casts them to their name and does a string comparison, which is pretty much worthless.

If all you're doing is storing the account names, then why would you need to use a TStaticVar(@account)?

Why would you assume I'm only storing an account name if I'm trying to use a TStaticVar? :p

I was just using that as an example, each obj has stats and other info stored against it and are held on the server; info is passed to the client and a GUI is updated. User interaction is based off the current state of the objects and list of objects.

I don't know how great it is a method of doing it but I was hoping I could do checkList() or similiar to check the element actually existed, and control access to addition / removal of objects or data.

Incorrect.

I just tested clientside, and it seems like I was right.

PHP Code:


		
			
temp.foo = new TStaticVar();

temp.foo.a = 2;

  

temp.bar = new TStaticVar();

temp.bar.a = 2;

  

echo(temp.foo == temp.bar); // echos 0

That doesn't exactly prove you are right.
My guess is behind the scenes TStaticVars and related objects have an id that it checks against with equality checks.

The quality of your post would increase ten-fold if you explained why it was incorrect.

As far as I know, GS2 uses strings as its internal data type which everything gets converted to and stored as (think arrays).

I'm just saying that the name is likely what it is checking for a comparison, since it is a string that will always be there, and GS2 likes strings.

There is no way to really know what the comparison is unless Stefan tells us, or someone writes a test case that is explicit enough.

I certainly wouldn't make use of any of the code posted in this thread because I don't know exactly what it is doing and it would also be unclear and potentially misleading to anyone else who looks at the code.
